It's possible, as the Food and Drug Administration is mulling a proposal to waive prescription requirements for commonly used drugs that treat conditions like diabetes, asthma, and migraines.

FDA regulators told reporters that easing access to obtain certain medications could help address undertreated epidemics, namely diabetes. According to the American Diabetes Association, of the nearly 26 million Americans with diabetes, an estimated 7 million don't even realize it and thus have not gotten diagnosed or treated. Diabetes is a leading cause of heart disease and stroke.

"These are discussions that need to start happening as we think about people's health needs and how to improve access," said FDA Commissioner Dr. Margaret Hamburg.

The over-the-counter switch is one of several FDA proposals aimed at increasing access to established drugs or speeding up approval of experimental medications.

After years of high-profile drug-safety cases in which the FDA restricted access to certain medications, the agency is increasingly highlighting its efforts help drugmakers get new innovative drugs on the market. The shift comes as drug companies and their congressional allies have pressured the agency to speed up approvals, complaining that U.S. requirements are more burdensome than elsewhere in the world.

"The world is changing and we have to change to with it," Hamburg said. "We're not talking about abandoning standards for safety and efficacy, we're talking about leveraging opportunities in science so we can do a more effective job as regulators and also improve the drug development process."

Over the years, the FDA has approved the switch of several high-profile prescription drugs to over-the-counter use. In 2003, the FDA cleared Prilosec, an over-the-counter version of the blockbuster AstraZeneca heartburn drug Nexium. The FDA only approves such changes if studies show that patients can safely take the drug after reading the package labeling.

Why haven't statins, which are taken by millions of Americans, been cleared for over-the-counter sales?

"We've had several applications already to switch statins to over the counter, and they have failed because consumers can't determine their lipid status," Janet Woodcock, head of the FDA's drugs center, told Reuters.

The new industry-backed proposal is driven in part by a wave of computer technology, including touch-screen kiosks found in pharmacies, designed to help patients self-diagnose common diseases. Drugmakers could use electronic questionnaires, diagnostic devices like blood pressure monitors and other computer-assisted technology to guide patients.

In some cases, patients would still need to see a doctor to obtain an initial prescription before getting over-the-counter refills. In other cases, patients would need to speak with a pharmacist but would not need a prescription to get medication.

The agency also says decreasing doctor visits could be beneficial.

"Eliminating or reducing the number of routine visits could free up prescribers to spend time with more seriously ill patients, reduce the burdens on the already overburdened health care system and reduce health care costs," the agency states in recent federal notice about the proposal.

Drugmakers would have to request a switch for each drug individually, and the FDA would judge the safety of each proposal on a case-by-case basis.

FDA officials stress that the idea is still in the early stages and a public meeting is scheduled for later this month to gather comments.

"We're not talking about very specific drugs right now, we're talking about the concept," said Dr. Janet Woodcock, director of FDA's drug center.
